Rosso are a road tyre plain and simple but probably a very good option. The full name of the ones I were shown are Pirelli supercorser v2 and I'm sure they are just an evolution of the original supercorsers. I will be buying sc1 front and rear and will post pics up when I get them (2 weeks), the price I have been quoted is 240 inc vat which I don't think is too bad.
